Is Mazuri diet the same as Marshall Farms food? I feed it to my "Sordo" ("deaf-one" in Spanish). It has high protein (38%) but also has ground yellow corn as the 2nd ingredient and corn gluten meal as the 4th ingredient (poultry by-product meal is the #1 ingredient). I saw on the "Ferrets Unmasked" video that rice flour is a higher quality protein than corn for ferrets and Iams kitten food uses rice flour. Actually I feed mine a mixture just in case. Any ideas??
